This;invention has g to do with awrench andA it is an obj ect ofthe invention toprovide an effective,l improved, quick, adjustable An object ofthisinvention is to providea quick 'adjustable wrench which is extremely simple andl convenient .to operate.-

itively set-when'the-jaws are in operative position. i provide a wrench ofy thevk character described whichyissimpl-e, e'ectiiffey and practical in construction. Y The objectsandfeatnres ofmypresent invention will .be Abest :and more? fully understood :from the following Vdetailed descripfy tion-,of a typical form and applicationot the invention, thronghoutwhich "description, rei accompanying drawings Fig. 1 is a'side elevationofa wrench embodying a. typical g formofthe presentin- Fig.2 is a sectionallviewof the wrench shown'in Fig. 1. j v

Fig.y 3 isan enlarged transverse' sectional .view taken' substantially as indicated by line 3,'-3 on Fig.v 1y showing the wrenchfin released position, thatis, in. position to allow foradjustmentfor'thegjaws, and i A Fig. tis aview'similar'to Fig'. 3 showing the wrench set or in position -or operation.

My present invention is.-in itsabroader sense,` applicable tok wrenches of lvarious typesand is capable of embodiment in various forms of construction. I have, 'for purpose of'illustration onjly,fchosen to set forth the invention in wrench of the type usually employedfor-handlingpipa and the like, vand have set forth a simple andtypical form of construction. It Vis to be .distinctly understood that the disclosure made in this application is not-to be considered as limitingf'the scope or rangeof applicationof my inventio.y

The tool illustrated inthe drawings includes, generally, a handle 10, a relatively stationaryjaw 11, anfadjustable Vjaw 12 and variousother parts.' the details of which will befhereinafterset i'orth.V rl `he handle `10 is A urther'object of-this invention is-to -moved by the spring, Y

designedsothat itsouter end-portion 13 forms a handle for the tool,jwhile-its inner portioncarries the working parts of the tool.

The handle 10 may, yasfar as the present invention is concerned, be designed and yconstructed'in' the manner usual to devices of this generalcharacter. Anotheriobject'ofthis inventlon'is to'lprovidefa quick, adjustable wrench which is pos The vjawll is a stationary-jaw connected or` formed with the `handle 10. In the particular case illustrated in the drawings, the

- jaw isrigidly mounted on the inner Vend of `the handle 10. Y The jaw is formed separate A with lthe handle 10,' so that-it isfadrjnstable i toward and away from the jaw 11.l In the particular type ofwrench illustrated in the drawings the javv-v 12 is connected with the handle 10 by meansof a shank 15 provided on fthe Vjaw 12 and a; carrier l16 whi`ch is provided on` the handle 10 .and carries thershan'k. 15. The shank 15 is preferably formed with the jaw 12cand is substantially vparallel with the handle 1 0.k l'l`he`carrie'r'16 provided on.y

vor in connection with, the handle 10 isin substance a part or continuation of the handle 10.1 In the particular'construction shown e .in the drawings the ycarrier '16 is-formed separately from the handle. and is connected thereto by a pivot pin 18,- The carrier and handle are related so that the carri-er hasa limited pivotal movement with reference to the lever. The'carrierextends longitudinally of the lever and is located-at Vtherear of the handle as Vclearly illustratedin Fig. `1 of the drawings. The pivotal connection between the 'carrier and handle is at the inner end of the carrier,y A spring 20isar ranged in connection Awith .the otherl end of the carrier .to normally vyielvdingly' holdit laway `trom the handle. VProjections v21 on the` carrierl cooperate with stops 22-on the handle to limit thefamount lthe1ca'rrieris .In the preferred 'form of my 'presentin-f vention the shankfl of the jaw 12 is roundV in cross-sectional configuration vand is carried in a round Opening 24 in the carrier 16.

The shank is carried' in the Opening 24 so that it can be rotated and valso moved loning being provided with projections, the" jaw, a shank on the' movable jew 'freely carred in the opening, the Wall 'of said openshank being providedwith series of teeth to cooperate with the lprojections of the carrier7 the shank having a recess adjacent the teeth to receive the teeth; of the carrier, and a spring pressed plunger mounted 1n ther carriery to` extend into the opening and .19th day of Sept.,' 1924.
